"As far as the book goes, it was my story and it was very raw, as I meant it to be, but I know that some parts of it and some of the publicity really offended Mick and I regret that," Richards admitted, according to Rolling Stone.

Among other things, Richards characterized Jagger as "unbearable" and accused him of having a "tiny todger."

"In the 1980s for instance Keith and I were not communicating very well," the singer said. "I got very involved with the business side of the Stones, mainly because I felt no one else was interested, but it’s plain now from the book that Keith felt excluded, which is a pity."

Since the publication of the book, Richards said, the pair of aging rockers have had a number of heart-to-heart talks that have been "incredibly important" to the guitarist.

"He and I have had conversations over the last year of a kind we have not had for an extremely long time and that has been incredibly important to me," Richards said.

Alas, Jagger and Richards won't be sharing their blossoming bromance on the road anytime soon; as reported earlier this week, the group has postponed a tour celebrating its 50th anniversary until next year, reportedly because Richards is still suffering the affects of a 2006 injury he suffered after falling out of a tree in Fiji.
